The present invention relates to sorting machines and particularly of the type which is capable of eiecting sorting operations in accordance with the analysis of designations on records which are to be sorted.

In order to understand the position of this invention with respect to the prior art, a. brief statement will be given outlining the developments of sorting machines up to the present time.

The 'first form of sorting machine comprises a plurality of sorting pockets into which records are manually inserted in accordance with the designations on the records and which are indicated thereon so as to be visible and readable.

by a persen; In accordance with the classification designatons on these records the operator manually piaces the records in the desired pockets. This form of sorting machine, if it can be so-called, has obvious limitations, and is only utilized when it is desirable to sort records in accordance with a few. classifications, and further, this type of sorting operation is only utilized when time limitations is not an involved factor.

Further dvelopments in this art consistedin the devisement of means to enable the analysis of the .designations on the records, either by mechanical or electrical elements so that certain portions of the machine are responsive to the analysis and accordinglycontrol sorting operations of the machine. Upon the realization of this development further developments led to the construction of a sorting machine which included automatic card feed and also the automatic sorting of the records in accordance with the classifications of the designations. Such forms of -sortingmachines are well known in the art and their mode of operation and construction need not be explained in detail.

In order to obtain a general understanding of the operation of such forms of machine it is explained that in types of machines which are adapted to sort record cards in accordance with digits 'representedthreon and which are of different denominationalorders, sortng operations are initiated by causing sorting to be effected under controlof the digits of the lowest denominational order. 'I'his is selected by the operator by provi ding an initial correlation between the analyzng device and the card column of the lowest denominational order. The operator may then start sorting operations and the records will be drected into the sorting pockets until al] have been sorted whereupon the machine is stopped in its operation. By manual adjust ment the next higher denominational order of the card columns is selected for sorting operations and after the sorted records have been removed from the sorting pockets and re-placed in the supply hopper in the digital sequence in which they have been sorted, the second sorting run is effected. The above mode ofoperation is repeated until sorting has been successively effected under control of all the card columns. The repeated starting, stopping, and re-starting of the machine, with the required intervention of the operator to perform certain tasks or settings manually, prevented heretofore the high speed of sorting operations which is especially desirable when a large amount of werk is at hand.

It is, therefore, the main object of the invention to provide in sorting machines of the type last described, a number of improvements which will be set forth in detail hereinafter and which tand to the urther automatization of sorting operations so that the sorting operations will flow automatically without interruption and, when once initiated, will continue automatically until the sortingjob is completed.

An attempt to provide a machine of this type which has the same desirable characteristics with respect to automatic sorting operations has previ- 'ously occupied the attention of others skilled in the art, and a representation of one embodiment is shown in the German Patent No. 351,030. In the machine shown in this patent, sorting operations are efifected under control of designations which represent letters and the sorting arrangement is devised to automaticallyeiect a plurality of sorting runs so as to sort and re-sort the cards in accordance with the alphabetical designations to arrange the cards in a desired alphabetical sequence. Between successive sorting runs, a control card is passed through the machine which eiects the automatic selection of the next column which is to control sorting operations.

The arrangement disclosed in this patent is, however, objectionable in not only its construction, but also its mode of cperation. In this patent, in order to obtain the desired result it is necessary to effect sorting operations starting with the first card column at the left and contnue successive sorting operations column by column to the rght. This arrangement, of course, cannot be utilized in the present machine which effects sorting in accordance with the digits since for the desired sequence of the cards it is necessary to effect sorting operations comof the machine results in the construction of a.

machine which would not be practical for commercial use. 'I'his objection is furthermore augmented by the provision of a special pocket into which all of the sorted records are directed at the termination of each sorting run. This special pocket must, of course, be as large in capacity as the individual sorting pockets.

T accomplish the purposes of this invention it is a iurther object of the present invention to construct a sorting machine which is capable of enabiing sorting operations to continue automatically without interruption and to provide in this improved form of sorting machine an arrangement which overcomes the objections to the machines of the prior art, as has just been described.

More speciflcally, it is an object of the present invention to provide a sorting machine with two rows of sorting pockets and to provide a selectively controlled mechanism which is capable of efiecting the autmatic selection of one of the sets of sorting pockets after each sorting run.

A still further object of the present invention is to provide a sorting machine with two rows of sorting pockets and to effect, during the passage of a control card which is the last record of the records sorted during a sorting run, the successive selection of-the sorting pockets.

A stil l further object of the present invention is to provide a sorting machine with two sets of sorting pockets and to successively correlate them with the sorting mechanism so that during the time records are directed into one series of sorting pockets, records may -be removed from the other series of pockets and placed in the supply hopper so that sorting operations will automatically continue and without interruption of the operation of the machine.

A still turther object of the present invention is to provide a sorting machine with two series of sorting pockets and a selectively operated -mechanism which is responsive to the termination of a sorting run andrvhich will select the next series of sorting pockets\to be utilized and concomitantly select the next card column which is to control sorting operations.

A still further object of the machine is to provide a controlling device fox the driving means of the machine which is responsive to a change in a settable element eiected after sortform of record card capable of beingsorted by the present machine. Certain of"the fields of the record which are utilized for soiting control are particularl'y ident fied by crosshatching so as to call special attention to the fact that in such fields the zero is also represented by combinational holes.

Fig. 2 represents the preferred form of control card which contrcls certain novel functions to be effected by the present machine. These functions are performed under controlof perforations arranged along two horizontal rows. It will be noted that these perforations are different in their arrangement than the arrangement of the perforations shown in the code of Fig. 3 for representing the diierent digits.

General operation of the machine In order that the operation of the machine may be better understood as the specification progresses, a general description will be given of its mode of operation.

The series of records which are to be sorted are flrst placed in the supply hopper and the machine is conditioned so that sorting operations may be eifected under control of the iirst card column and which, in the present machine, is the column representing the lowest denominationai order digits. The operator then initiates the operation of the machine and sorting operations will be au tomatically efi'ected and the records will be d,#i ected to one series of sorting pockets. r

A special control card is placed upon the uppermost perforated record which is tobe sorted and When this control card passes through the machine there will be a change of sorting pockets and concomitantly the next column to con trol sorting will be selected and also the next series of sorting pockets will be correlated with the sorting mechanism. However, before the machine is conditioned in this manner the operator has taken some of the cards out of the sorting pocket and has inserted them in the supply hopper on top of the control card. Obviously, after the passage of the control card through the machine these records will be sorted thereby preventing any interruption of the operationof the machine. With the machine continuing in operation, the operator will remove the sorted records from the other sorting pockets and place them in the supply hopper in their digital sequence. The records are therefore re-sorted into the second set of sorting pockets and the same control card or another control card is placed upon the last perforated records of the second sorting run so as to continue the operation of the machine for effecting the third sorting operation.

bviously, the operator can be kept busy by taking the sorted records out of one series of sorting pockets, replacing them in the hopper so that the machine may continue automatic sorting runs under column by column control unti1 'all the necessary sorting runs have been efiected.

If so desirable, an indicator may be placed upon the machine so that the machine operator will recognize When the last sorting run is being effected and the operator will, of course, leave the record cards which are sorted during the last sorting run in the sorting pockets. After the last sorting run has been efiected, the control card again passes through the machine and the next series of sorting pockets will be selected, but in this case, since no more records will pass through the analyzing device, means will be responsive to this condition in the machine to cause the automatic termination 'of the operation of the machine. By taking the records out of the sorting pockets from the series presented to the operator after the cards have been sorted ior the last time, and. placing them in a single stack in a digital sequence, the record cards will be found to be finally sorted in a true serial numerical order.

Sorting operations of the machine Mounted beneath the base plate II of the machine is the driving motor |2 (Fig. the armature shaft of which drives through a belt connection l3, a spindle |4 which is provided with worm wheel portions, as best shown in Fig. 9. The worm wheel portions of spindle l4 drive the plurality of sets, of card feeding rollers l5 which are best shown in Figs. 5 and 6.

The record cards which are to be sorted are placed in a supply hopper I6 (Fig. 6) and by means of a rec'iprocable picker I! the cards are fed singly from the bottom 01' the supply hopper to the analyzing brushes l8, the leading edge of the card then being engaged by the second set of card feeding rollers [5. When the perforations of the selected card column, which is to control sorting operations, are operativeiy re- 75 lated to the plurality of analyzirig brushes i8 an electr-ical impulse is directed to the brushes 3 in order to effect the analysis of the perforations to control subsequent sorting operations. In accordance with the analysis of the card perforations sorting operations are eflected during a subsequent cycle of machine operation.

The sorting of the card is eifected in a manner which is well known in the art and includes a. plurality of sorting blades |9 which terminate at their left ends at the respective sorting pockets. When the card leaves the analyzing brush es I8 it is fed to the sorting blades I9 and the card is interposed between the right ends of the sorting blades and an armature 22 (Fig. 10) of a sorting control magnet 2I. The latter has directed to it,.at a diflerential time in the cycle of machine operation, an electrical impulse which causes the energization of the sorting magnet 2! and the latter will draw its armatre 22 downwardly. At this time certain of the sorting blades will be held up by the leading edge of the card and certain of the sorting blades will drop downwardly due to the lowering of the armature 22. This will cause a separation between certain of the sortlng blades and the card will be directed under control of these sorting blades until the card reaches a sorting pocket into which it is to be sorted.

Referring to Fig. 14, When the sorting magnet 2! is energized a relay |36 will also be energzed and the latter will close stick contacts l3'l thereby retaining the energization of the sorting magnet 2l, this stick circuit being closed through cam contacts II5. At the end of the cycle in which a card is sorted cam contacts H5 will open thereby effecting the deenergization of the sorting magnet 2! and the relay magnet l36. The above described mechanism for sorting the cards is only generally described herein as it is well known in the art andis fully shown and described in the patent to Michael Maul, No. 2,025602 dated December 24, 1935, to which reference may be had for further details of construction and operation.

However, in the present machine, there is provided two rows of sorting pockets which are best shown in Fig. 11 and are designated by the reference numerals 20a and 2012. The two rows of sorting pockets are longitudinally arranged and are supported by a carriage which may be reciprocated so as to selectively correlate the desired row of sorting pockets.with th sorting blades l9 so that in one sorting run one row of sorting pockets may receive the sorted cards, and in another sorting run,ifor the next card column, the other row of sorting pockets may receive the cards to be sorted. The manner in which this is per formeel will be subsequently described in detail.

Manual selection of initial card column which is to control sorting operatons The manual selection of the first card column which is to control sorting operations is eifected in a manner which is well known in the art but will be described herein in some detail. Referring to Fig. 7, it will be seen that the analyzing brushes are supported by a carrier 26 which is threaded so asto receive a threaded portion of a spindle 23. At one end of the spindle 23 there is secured a crank handle 24 one revolution of which is adapted to displace the analyzlng brushes l8 laterally the distance of one card column.

As shown in Fig. 7, the ends of the spindle 23 have attached thereto a. plurality of cams which cooperate with stationary rollers 25. As the spindle 23 is initially rotated by the crank handle 24 the cooperaton of the cams with the rollers 22 will first elevate the brush holder 28 so as to position the brushes I8 above the card, and as the crank handle is further rotated the brush carrier 28 will be shifted laterally so as to correlate the brushes l8 with the next card column, and when ths correlation is obtained further rotation of the cams by the crank handle will permit the lowering of the brush carrier 28 so that the brushes I8 will now engage the perforations at the next card column. The above ar-- rangement is so designed that a single revolution of the crank handle will eiect the lateral positioning of the brushes I8 to the extent of one card column.

Successive automatic selection of card columns which are to control so1ting operations The last described setting devices are employed for the purpose of efiecting the manual positioning of the analyzing brushes [8 to the first card column which is to control sorting operations. When sorting operations have been effected under control of the first card column it has been the usual custom to select the next card column by the manual positioning of the brushes I8 in the marmer just described. In the present machine the selection of successive card columns is efiected automatcally and without attention of the operator. The means for accomplishing this functon will now be described in detail.

Referring to Fig. 10, t will be noted that one of the threaded portons of thespindle 14 is adapted to drive through an idler gear a gear which is integral with a sleeve- 31. The sleeve 37 is loosely mounted upon a shaft 38 and the sleeve 31 is provided with an integral disc 35 which is provided with a notch 34 (sec Fig. 9). Secured to the shaft 38 is a disc 38 upon which is pivotally mounted a clutch pawl 39 which is adapted upon its release to be urged by a spring so that a tooth 42 of the pawl will enter the notch 34 thereby efiecting a clutch engagement between the disc 35 and the disc 36.

The release of the clutch is efiected by the energzaton of a magnet 4l. When the clutch control magnet 4! is energized the armature thereof, which is formed as a latch arm 40, is drawn downwardly s0 as to release the pawl 39. The latter is then rocked by a spring so that the tooth 42 will engage the notch 34 of the disc 35. This will effect a clutch engagement so that the shaft 38 will be rotated a complete revolution.

At the termination of the single revolution of the shaft 38 the pawl 39 will be engaged by the extremity of the arm 40 which is now at its normal position thereby disengaging the tooth 42 of pawl 39 from notch 34 and this disengagement will be retained until magnet 4! is subsequently energized.

Secured to one end of the shaft 38 is a gear 30 (see Fig. 8) which meshes with a gear 29 upon which is pivotally mounted a pawl 3I which is adapted to engage a notch formed in the hub of the crank handle 24. Obviously, by eiectng a single revolution of the shaft 38 the gear 28 will be rotated clockwise through the intermediate gear 30 a complete revolution so that th rough the pawl 3! the crank handle 24 will be rotated a complete revolution. Ths will, by the means previously described, laterally displace the analyzng brushes 18 the dstance of one card column and this operation will be eiected automatically by controlling means which will be subsequently described in detail hereinafter.

Referring to Fig. 7, it will be noted that the brush carrier 26 is provided with a block 21 of insulating material which is adapted, after successive movements of the carrier 26, to engage one blade of contacts 28 and open the latter. From Fig. 7, it will be noted that contacts 28 are adjustably mounted upon a serrated bar and the contacts 28 are so positioned that after the sorting operationshave been efiected for the last card column the movement of the carrier 25 one step to the right, as shown in Fig. 7, will through the block 21 cause the opening of contacts 28.

The function ofthe contacts 28 will be subsequently described in detail.

Au tomatit: selection of rows of sortng pockets The present machine is preferably equipped with a selecting mechanism whereby the rows of sorting pockets may be automatically selectednclconcomitantly with the successive selectlon of the card columns which control sorting opera- The successive selection of the sortingj pockets is efiected by mechanism operated by the shaft 38 whch,it will be recalled, is driven" a complete revolution upon the releaseoi the clutch which is controlled by the magnet 4 I.

tiens.

Referring to Fig. 10, it will be seen that shai't 38 has a bevel gear connection to a vertlcally mounted shaft 44 and the latter, in turn, has a bevel geer connection with a transversely mounted shaft 45.

The carriage which carries the sorting pockets is best shown in Figs. 11, 12, and 13 to which attention is specifically directed. As previously stated, the machine is provided with two lo'ngitudinal rows of sorting pockets, deslgnated 2lla and 2012 in Fig. 11, each row of pockets consisting of ten pockets and each pocket having a. resil iently mounted base plate 52 (Fig. 6). The two rows of sorting pockets are supported by a 1' shaped bracket plate 53 which is shown in section in Fig. 12 and in plan view in Fig. 11. The sorting and 59 are secured to ther respective shafts 50 and 6I which are mounted in the base plate II of the sorting machine. The shafts 60 and 81 are interconnected by a shaft 84 which carries at the ends thereof beveled gears meshing with respective beveled gears 62 and 63 attached to the shafts 60 and lil, respectively. The bevel gear 63, which is secured to the shaft 6| has a bevel gear connection to a shaft 45 and the latter, as previously described, has a bevel gear connection to the shaft 44 (see Fg. 10).

It will be recalled that upon the release of the clutch which is controlled by the magnet 4I shaft 38 will be rotated for a single revolution. The operative connection between the shaft 38 and the shafts and. 6! is such thata rotation of shaft 38 for a single revolution will effect the rotation of the shafts 60 and 61 en angular movement of Referring to Fig. 11, it will be seen that relating the other set of sorting pockets with the sorting mechanism so that cards will be sorted into these pockets under control of the next card column which is selected concomitantly with the positioning of the next set of sorting pockets to be utiiized.

After cards have been sorted into one of the sets of ten sorting pockets during one sorting run, the operator will remove the cards from these sorting pockets and replace them in the. suppiy 'hopper thereby enabling the sorting pockets which havebeen emptied to receive cards which are sorted under control of the successiv e card column during the next sbrting run.

Explanaton of circuit dagrdm and marmer of operatonoj the machine In order to carry" outsorting operations in the manner previously described the operator first places a stack of cards to be sorted in the supply hopper I6. On top of theperforated 'cards which are to be sorted the operator places several blank cards end upon the uppermost blank card there is placed the control card which is shown i nFig. 2. The above arrangement of.

aards is"made for a rea.son which will be apparent later on as the descriptibnof the operation of the machire progresses. Before the operator starts; the machine ther'e will be a preliminaryadjustment o1' the;machirie so as to select the card fleld to select the particular-card column of the sel'ected cardfield.

' I'he selection of the card column is effected,

as previouslydescribed, by the rotationof the at a time when the perforations of the upper card field are beneath the brushes l8 thereby closing the circuit at such time to the contact plate H16. However, if the switch N15 is positioned en as to engage a contact point connected to cam controlled contacts l04 -ancl circuit will be closed through contacts IM to the contact plate I06. The contacts l04 are closed by a cam at a time When the perforations of the lower card fleld are beneath the brushes l8.

The present machine is adapted to effect the sorting of records of the type shown in Fig. 1 in which it will be noted that the digits are represented by the combinational hole system. The machine is preferably constructed so as to eiect the analysis of the cornbinational holes in one sorting cycle and then in a subsequent sorting cycle effect the sorting operations. While this sequence of operation may be carried out by different forms or means, it is preferable to effect thi operation by the utilization of the two sets of storing devices. One set of storing devices is adapted to receive and store up the representation of the combinational holes analyzed and this result is transferred to a second set of storing device so that the latte!" may control a sorting operation in the successive operating cycle. After the transfer operation has been effected, the flrst set of storing devices is cleared out so as to receive azid store up the result of the analysis of the-next card to be sorted. After the sorting operation has been eflected undercontrol of the second set of storing devices the letter is cleared out so-as to control sorting operations for the next card.

' The above described set-up mechanism is well known in the art and is fully shown and described which is to control sorting operations and also crank handle 2l,shovqn in Flg. 4, which-pbsitiorisfl the brush holder so as to coordinate the analyzing brushes l8 with aselected card column. The selection of the card fielcl is efi'ected by snit ably positioning a lever I 05 (Fig. 14) which selects a desired card field bymeans which Wi1l be presently describecl.-

When these two preliminary adjustments have been made, the operator will initiate the operation of the machine by the depression of a start key 200 which, it is evident from Fig. 14, will close the circuit from the positive line side HJI through the contacts closed by the start k ey 200, through the control contacts 28, to the motor |2 to the negative line side #0. When the first card has been fed out of the supplyhopper it will immedately close card lever contacts H12 thereby providing a stick circuit for the motor 12 enablng the release of the start key 200 butinsuring the continued operation of the driving 'motor as long as cards are being fed from the supply hopper.

Current to the analyzin'g brushes |8 is transmitted from the positive line side HH through the card lever contacts It2 to either of two circuits depending upon which card field is to control sorting operations, such card fields being selected, as previously described, by the switch I05. With the switch N15 in the positio n shown in Fig. 14, current will be transmitted to the brushes l8 by the following described circuit: from the positive line side I N, card lever contact 12, to cam controlled contacts |03, switch 105 to the contact bed plate 106. Contacts |03 are closed by a cam in. the patent to Michael Maul No. 2,025,602, dated December 24, 1935. The present arrangement also utilizes relays for receiving and storing up representations of the combinational holes but differs from that shown in the patent by causing the-above described transfer operation to be effected electrically.

From F'ig. 14, it will be seen that from the brushes |8 there are electrical connections by wires III to respectivereleys H2. All of said relays have a common wire connection H'I to the negative line side H 0.

Frm Fig. 14, it will be noted that relays H2 aredesignated by the Roman numerals I toIV and from Fig. 3 it will be seen that the combinational hole designations are also identified by the corresponding Roman numerals. Thlls the energization of those relays H2 will be effected which correspond in designation to the combinational holes analyzed.

Each relay H2 when energized will attract its armature H3 thereby closing a stick circuit for the energized relay, this stick circuit being closed from the positive line side I 0! through contacts H5, wire H6, the armature H3 of the energized relay, the wire H 4; the energized relay H2, wire H1 to the negative line side H0. Hence the relays which are energized will be retained energized until-cam controlled contacts H5 subscquently open, and which may be effected after the transfer operation.

The armatures H3 are connected to armatures I2I of the relays |22 of the second set of storing devices by connecting links l2l). Obviously, the energization of a relay H2 will eilect the movement of an armature 12! to closea circuit connection which will energize a corresponding relay I'22 by the following described circuit: from the positive line side Ill, wire lil, one of the relays ation between the relay 2 to the relays |2l and the energized relays I22 will close stick circuits which lead trom the positive line side IIII, a common line connection I2l for relays I22, an energized relay in to en armature IN the same relay, to a contact point engaged thereby, a wire I'2'l, to cam controlled contacts in, to the; negative line side IIO. Cam controlled contacts 129 are closed during the transfer operation and are retained closed en as to keep the energized relay; I22 energized until the completion of the sorting operation which is eflected under control of relays 122.

'I'he translating mechanism provided herein is 01' the type which is well known in the art and tully shown and described in the aforementioned patent to Michael Maul, No. 2025602 dated December 24, 1935. mechanism is adapted to eflect the translation of the combinational hole representations set upon the relays l22 into a single controlling electrical impulse. As best shown in Fig. 14, when one of the relays in is energized a related bar In general, the translating l will be elevated and thiswill cause the openin; of. certain contacts I3I and cause theclo-- sure of other contacts I 3l. The py 'amidical arrangement of contacts I3I and interconnections are such that by closing difierent contacts III and opening other contacts, one of a series of;

ten diglt lines l3l, marked 1 to 9 and 0 in Fig.

14, will be selected. Coordinated with the digit lines I" is a commutator MI which is timed with the card teed in such a manner that as the leadwill thereupon terminate.

clutch control magnet 4I, to the negative line side IIII. The energization of the magnet I! will initiate the i'unctions above described.

Attention is directed to the iact that when contacts I3I are opened by the relay masnet I22 designated I the circuit will -be closed to the line i" and no circuit will be closed to the commutator I4I so that .during the subsequent sorting cycle the sorting magnet I! will remain deenergized. This will cause the control card to be directed to a reject pocket designated by R. in lls. 4. This sorting pocket is the usual reject pocket of a sorting machine. In the present arrangement it is preterable to have this pocket located 01! the carriage and. theretore. always in cooperation with the sorting blades.

Recapitulating, after the initiation of the operation of the machine, sorting operations will be automatically eflected for the first card eolumn, which comprises the lowest denominational order, and the records which are sorted under control of the iirst card column are selectively directed intd one set of sorting pockets. These records are then taken out of the pockets, replaced in the supply hopper in the sequence of the digits 0-9 and then under control of the succeeding card column, these records are resorted by being direoted into the other set of sorting pockets, and so on. In this marmer. sorting operations are automatically effected i'or successive card columns and atter the sorting operation has been efiected under control of the last card column of the record cards the cards will be arranged in serial numerlcal order, and contact 28 will be opened in the manner previously described thereby opening the circuit to the drlving motor and sorting operations After a sorting run for the last card column there is a change in position of the carriage and the pockets receivin; the records sorted in the last run are preins edge of the card approaches the ends of the be withdrawn by the operator and then stacked sorting blades l9 an electricalimpulse will be transmitted to the relay magnet |36 and the sortenergized. Contacts I|I are prei'erbly timed to open after the transfer has been eii'ected from the reiays H2 to the relays l22 thereby conditioning the relays li2 so that they may be subsequently energized to receive and store up the combinational hole representation of the subsequent card to be sorted.

It will be recalled that the control card shown in Fig. 2 is adapted in its passage through the sented to the operator enabling the records in in the digital sequence in which they are sorted.

The operator of the machine wiil, therefore, before there is a change of sorting pockets. take the records out of the 0" pocket and immediately replace them in the supply hopper. Duranalyzing nieans of the machine to eflect the energization of the clutch control magnet ll thereby causing concomitantly the selection of the next sorting column and also the other row of sorting pockets. During the passage of the control card, relays I l! designated by I and IV will be energized and the set-up willbe trans- !erred to relays l22 designated by corresponding relays I and IV. 'I'he set-up of the last mentioned relays will effect the closure of certain of the contacts I3l to cause the closure of a circuit leading from the positive line side IOI, wire l32, contacts IJI closed by relay IV' to contacts I II closed by relay 1. to a wiro l", thence to the ing the cycle of machine operation the control card passes through the machine the next set of sorting pockets will be selected and since periorated records will immediately i'ollow through the analyzing means, sorting operations will automatically continue under control of the next card column. In the event that there is passed 'through the machine cards which are not perforated, these record cards will be directed into the reject pocket designated R. in Fig. 4. If the operator so desires, the same control card may 'be utilized for successive sorting runs but in some instances; it may be desired to have on hand a number of these control cards so that they may be placed in the supply hopper at the termination of each sorting run without the necessity oi' removing them from the reject pocket R into which they will be normally directed.

Attention is directed to the iact that it is preterable to place a tew blank record cards upon the last peri'orated record card to be sorted in each sorting run, thereby delaying for a iew cycles of the machine the operation of the mechanism which eifects the automatic selection of the next set of sorting pockets to be utilized and the selection of the next card column to control sorting operations. These imperiorate records wiil, of course, be directed into the reiect pocket R. 'I'he above arrangement is preferably followed because it will insure that all the peri'orated record cards utilized in one sorting run will be directed into the sorting pockets before there is a change in the position of the carriage carrying the two series of card pockets, or a change in the Dsition of the carrier 26 so that the brushes i! will be operatively correlated with the next card column.

While there has been shown and described and pointed out the i'undarnental novel features of the nvention as applied to a. single modificatign it will be nnderstood that various omissions and substitutions and changes in the form and details the device iliustrated and in its operation may be made by those skilled in the art without departing trom the spirit of the invention. It is the intention, therei'ore. to be limited only as indicatd by the scope oi' the tollowing claims.
